Brood VII (17-year)
The Onondaga Brood
Brood VII contains only M. septendecim and is currently found only on the Onondaga Nation in upstate New York. Populations near Rochester seem well documented, and several collections exist from Great Gully populations. However, the brood appears to be contracting. For more information see: (Cooley et al. 2004; Pechumen 1968; Pechumen 1984).
Brown symbols on the map above were generated from verified records in the Cicada Central Database on 20 January 2013.
Blue symbols on the map are based on Marlatt (1923).
Gold symbols are based on Simon (1988); smaller symbols are records with a lower degree of certainty.
These records have not been field checked.
A project is currently underway to make new maps of periodical cicada broods. See the Magicicada mapping project homepage and the Geospatial Data Clearinghouse.
